2v Claims. (Cl. 126-194) This invention relates to improved means for hingedly mounting the doors of stoves` and the like.

Ileretofore it has been the practice for stove manufacturers to assemble stove doors and frames to the stove body at` the same time. It was, therefore,Y impossible to assure of the doors being level and straightand the necessary adjustments thereto often resulted in the enamel parts of the stove and doors being damaged or marred.

The principal object of the present invention is to equip stove doors and the like with adjustable hinge pin brackets to permit of the doors being made up as a subassembly independently of the stove itself and thereafter mounted on the stove by the manufacturer whichA tends to reduce breakage and damage to the stove body and doors to a minimum.

Another object is to provide a stove door with adjustable hinge. pin brackets which permits of the door being assembledby use of. a jig thereby assuring of the door being level and straight. and permitting the door to be assembled independently of the stove.

Another object is, to provide. slidably mounted hinge pin bracketsv on stove doors which permit of easy assembly and disassembly and adjustment thereof to assure of a proper and uniform t.

A further` object is `to provide hingeV pin brackets for stove doors which may readily be adjusted to retain the hinge pins in the4 desired engagement with the stove body.

These and further objects and advantages will be apparent asthe specification is considered in connection with the accompanying drawings wherein:

Figure 1 isa rear elevationof a door and frame embodying my invention;

Figure 2 is a vertical transverse sectional View on the line 2.-2. of Figure. 1 showing the door in closed position;

Figure 3 is an enlarged. vertical fragmentary transverse sectionalviewofa portion of the door and frame;

Figure 4 is a fragmentary longitudinal section on the line 4-4- of` Figure 3, showing the hinge pin bracket and pin andthe adjustable mounting on the door frame;

Figure 5 isv a vertical. fragmentary sectional view on the line 5-5 of Figure 4; and

Figure 6 is a perspective view of one of the hinge pin brackets.

Referring more particularly to the drawings wherein like reference characters designate similar parts throughout the several views, the numeral I- refers generally to a rectangular metal door frame having; a doorand drawer openings 2 and 3 therein, as illustratedV in Figure 1'. The outer marginal edge of the frame I is bent rearwardly, as at 4, to permit of theA frame being seated within an opening inthe frontv of the stove frame, not shown, and securedv thereto in any suitable manner by fasteningV devices such as screws or the like, also not shown. It will be understood that a drawer, not shown, is-adapted tor be slida-blyfpositioned within the frameopening 3 and to extend into thefstove body in a4 conventional manner.

A door 5; hingedly mountedn in the frame door opening 2 ina mannerr hereinafter described,

comprises a'front sheet metal enameled plate 6" and a rear sheet metal plate l. The edge portionsof the front plate are bent rearwardly to form a continuous peripheral flange 8V which is adapted to overlie andl fit closely with a forwardly extending peripheral'flange 9 formed on the rear plate. The flange 8 extending along the bottom of the front platey is provided with-anY upturned flange I0; which engages with the lower edge ofr the rear plate 'I and serves to holdv the plates The plates; are clamped together by'- together. spacedscrews orthe like I I. Insulatingmaterial I2,l is preferably interposed in the space-between the front and rear platesfaccording to Well established practice.

The door 5 is hingedly connected to the door frame by my improved concealed hinge construction comprised of two substantially L shaped metal hinge brackets I 3. As `the brackets I3' areidentical only one will be described. Thus each bracket I-3 isaformed' with a substantially horizontal hat' basen portion. I4 and an upwardly extending side portionV I5, and isv slidably con-` nected to the back' plate; 'I in a manner hereinafter described. They inner end of ametalihinge pin I6', is snuglyv and immovably fitted into one of two apertures I'I--I'l extending through the upper end o fV the side portion I5 ofthe bracket I 3'. The pin may be press fittedv or otherwise secured within the aperture, as by welding or thereof, as best illustrated in Figures 1 and 4, to permit of a screw or the like being inserted through the aligned slots and apertures for clamping the hinge brackets in desired adjusted position on the door. Hinge pins I6 are aligned with and project laterally through apertures 2I in the side peripheral flanges 9 of the rear plate 1, and extend through apertures 23 in the lower end of an extension 24 depending from each of two brackets 22 and projecting forwardly through a vertical slot 26 in each of the side portions of the stove door frame I. The brackets 22 are secured to the frame I by any suitable means such as screws or the like 21 so that the hinge pins IE serve to hingedly mount the door on the frame.

In order to facilitate the opening and closing of the door, two downwardly depending curved webs 28 having upturned lower ends 29 are formed on or suitably attached to the side peripheral iianges 9 of the rear plate 1. Springs 3l, anchored at their lower ends in openings 32 in the lower end portion of frame I, are attached at their upper ends to the bent lower ends of metal fastening clips 33, the bent upper ends of which are in turn hooked overV the lower ends 29 of the webs 2B. It will, therefore, be apparent that the springs serve to yieldingly retain the door in closed position. The springs 3l and clips 33 may readily be connected to and/or disconnected from the webs 28 when assembling andv disassembling the door. The lower ends 29 of the webs are provided with shoulders 30 adapted to engage with the rear face of the door frame I and limit the opening movement of the door 5.

It is important that each of the side and base portions of the brackets I3 be provided with two openings I1-I1 and I 8-I8' as this permits of the brackets being interchangeable. That is, when a bracket I 3 is mounted, as previously described, on the left side of the door, viewing Figure 1, the hinge pin I 6 will be positioned in the opening I1', to permit of the pin being aligned with andextended through the opening 2I in the flange 9 of rear door plate 1. The attaching screw 20 will extend through the opening I8' in the base portion of the bracket. On the other hand, when a bracket I3 is mounted on the right side of the door, viewing Figure 1, the bracket will be oppositely arranged from the left hand bracket, so that the hinge pin I6 must necessarily be positioned in the opening I1 to align the pin with the opening 2l in flange 9 and permit the same to extend therethrough, and the attaching screw 20 will extend through the opening I8 in the base portion of the bracket. It will, therefore, be understood that the provision of four openings I1-l1 and I8-I8 in the brackets permits of the same type bracket being mounted on bothsides of the door. This reduces manufacturing costs and facilitates assembly and disassembly of the hinge pin brackets, in an obvious manner.

As the screws 20, used in connecting the hinge pin brackets I3 to the rear door-plate 1, extend through the longitudinal slots I9 in the plate 1, it will be understood that the brackets I3 may be readily moved for adjusting the hinge pins I6, by loosening the screws. This is particularly desirable because it permits of the stove door being assembled as a subassembly unit independently 4 of the stove. In such cases, the door will be completely assembled by the manufacturer with the hingel pin brackets mounted thereon, which enables the complete door unit to be readily 5 mounted on the stove as a unit prior to shipment.

Assembly of the door on the stove is readily effected by adjusting the hinge pin brackets, so that the pins interconnect with the stove frame brackets 22, and thereafter tightening the hinge pin bracket screws 2i) and finally securing the clips 33 and springs 3i in place.

It is to be understood that various changes may be made in my invention Without departing from the scope and spirit of the appended claims.

Having thus described my invention what I claim is:
